On processing of full-scale tests' results considering trajectory observations of manoeuvres
The new approach to processing of full-scale experiments' results on vessel manoeuvring has been proposed. It includes more complete using of the manoeuvre trajectory information, that allows to obtain all kinematic characteristics. The processing uses a spline-approximation of the trajectory parametrized by time, and allows to smooth the influence of the observation result errors to some extend. However, the method claimes a rather rigid requirements to the level of these errors and it leads to the further perfecting of the vessel observation tools (for example, using of DGPS or GPS P-code).

The calculation model of strike risk at mooring
The paper considers the possibility of the strike of vessels moored to each other in the open sea from the point of view of their safety. The dependences defining mathematical expectation of a part of the moored vessel trajectory leading to a dangerous approach of vessels and possible strike have been obtained. The model of an interval estimation has been designed for increasing the veracity of the strike prediction.

An algorithm of calculation of geometric parameters of underwater and above-water parts of a vessel
The solution of a number of practical and theoretical tasks concerning determination of the vessel navigability requires rather extensive calculations of parameters depending on geometric characteristics of underwater and above-water parts of a vessel. The author has proposed an algorithm of calculation of vessel hydrodynamic and aerodynamic characteristics on the basis of its theoretical and general drafts. The algorithm has been worked out for parameters of the mathematical model of the "Astrakhan" type tanker.
